I'm looking to build a private site network of long tail keyword sites. Can anyone recommend a good platform to build and manage all the sites (200 to start with). We been using wordpress with managewp but it's a lot of work having to keep updating and taking care of different themes. also slow loading times. Basically the plan is to build 200 sites in couple of months ( different ips, hosts, and registrars), build back links to sites separately, and slowly, once they gain some pr link them to money sites (about 30 so far). The only problem is that i need to find a better way to build and manage the supporting sites network with something other than WP, joomla etc with something faster, easier to manage and not traceable ( a big problem with WP) Thanks!
